Each preference is a token, some whitespace, and a value. A value can be a * integer * boolean: integer which is exactly either 0 or 1 * float: period separated decimal value * string: sequence of characters, without quotes * fvec[n]: space separated list of n floats * ivec[n]: space separated list of n integers * color_3: space separated list of 3 floats or integers between 0 and 1, representing RGB values. * color_4: space separated list of 4 floats or integers between 0 and 1. The first three are RGB values, and the last one is opacity. text_highlight_color color_3 Highlight color when text is selected using mouse. vertical_line_color color_4 Color of the highlight bar when right click is pressed (to bring up the reading guide). Alias preference: visual_mark_color. search_highlight_color color_3 Highlight color when text is a search match. link_highlight_color color_3 Highlight color for PDF links (note that highlight is off by default and can only be seen by performing a toggle_highlight command. See keys.config for more details). synctex_highlight_color color_3 Highlight color for synctex forward search highlights. background_color color_3 Background color. dark_mode_background_color color_3 Background color in dark mode. dark_mode_contrast float Contrast in dark mode. Higher values render the PDF with dimmer text. default_dark_mode boolean Start in dark mode if 1, light mode if 0. item_list_prefix string Text to prefix every bookmark in bookmark lists. inverse_search_command string The command to use when trying to do inverse search into a LaTeX document. Uncomment and provide your own command. %1 expands to the name of the file and %2 expands to the line number. zoom_inc_factor float The factor by which we increase/decrease zoom when performing zoom_in or zoom_out. vertical_move_amount float How many (screen) inches we move vertically/horizontally when per- forming move_up/down commands. horizontal_move_amount float How many (screen) inches we move vertically/horizontally when per- forming move_left/right commands. move_screen_ratio float How many inches we move vertically/horizontally when performing move_left/right commands. flat_toc boolean If 0, Table of Contents is shown in a hierarchical tree, otherwise it is a flat list (can improve performance for extremely large table of contents). should_use_multiple_monitors boolean If it is 1, when launching the application if we detect multiple monitors, we automatically launch the helper window in second moni- tor. should_load_tutorial_when_no_other_file boolean If the last opened document is empty, load the tutorial pdf in- stead.. should_launch_new_instance boolean If it is 0, then we use the previous instance of sioyek when launch- ing a new file. otherwise a new instance is launched every time we open a new file. should_launch_new_window boolean Open the file in a new window but within the same sioyek instance. should_draw_unrendered_pages boolean If set, we display a checkerboard pattern for unrendered pages (by default we display nothing). check_for_updates_on_startup boolean If set, shows a notification on startup if a new version of sioyek is available. sort_bookmarks_by_location boolean If set, we sort the bookmarks by their location instead of their creation time. shared_database_path string Path to shared.db database file. If not set, we use the default path. you can set this to be a file in a synced folder (e.g. drop- box folder) to automatically sync sioyek across multiple computers. On GNU/Linux, this refers to ~/.local/share/sioyek/shared.db. hover_overview boolean Displays an overview of destination when hovering over a link with mouse (no need to right click). visual_mark_next_page_fraction float When moving to the next line using visual marker, this setting spec- ifies the distance of the market to the top of the screen in frac- tions of screen size. visual_mark_next_page_threshold float When moving to the next line using visual marker, this setting de- termines at which point we move the screen. ui_font string Font to use for user interface (file browser, bookmarks, etc.). font_size integer Font size middle_click_search_engine string Search engine to use for middle click lookup. This value should be a string corresponding to the letters, *, in another string preference which specifies the url, search_url_*. For example, * search_url_g https://www.duckduckgo.com/search?q= * middle_click_search_engine g Will use the duckduckgo address for middle click search. shift_middle_click_search_engine string Search engine to use for shift middle click lookup. Value is analo- gous to middle_click_search_engine. startup_commands string Semicolon separated list of commands to run on startup. status_bar_font_size integer Font size for text in the status bar. custom_background_color color_3 Background color to use when executing the command toggle_cus- tom_color. custom_text_color color_3 Text color to use when executing the command toggle_custom_color. rerender_overview boolean If 0, we use the previous renders for overview window which may cause it to be blurry if it is 1, we rerender with the proper reso- lution for overview window which looks better but may increase power consumption. wheel_zoom_on_cursor boolean Normally mouse wheel zooms in on the middle of the screen, but if this is set to 1, we zoom in on the cursor. linear_filter boolean Apply linear texture filtering by passing GL_LINEAR to glTexParame- teri. This means that for a pixture being textured, we use the weighted average of the four texture elements closest to its center. display_resolution_scale float Resolution multiplier for PDF viewer. status_bar_color color_3 Color of the status bar background. status_bar_text_color color_3 Color of the status bar text. main_window_size ivec[2] Default size (in width and height) of the main window when a helper window is opened. You can copy the value of this config using the copy_window_size_config command. If this is not set, then we use the full size of the first screen if there are multiple monitors, otherwise we use half of the width of the screen and the whole height -- a vertical split in half. main_window_move ivec[2] Location to snap the main window to in x and y co-ordinates when the helper window is opened. If not set, use (0, 0), top left of the first screen. helper_window_size ivec[2] Default size (in width and height) of the helper window when it is opened. If not set, use the full size of the second screen if there are mul- tiple monitors, otherwise use half of the width of the first screen and the whole height. helper_window_move ivec[2] Location to snap the helper window to in x and y co-ordinates when the helper window is opened. If not set, then use (first screen width/2, 0) if there is only one monitor, and (second screen width, 0) if there are two. touchpad_sensitivity float Touchpad sensitivity. page_separator_width float Width of the page separator. page_separator_color color_3 Color of the page separator. single_main_window_size ivec[2] Default size of the main window when the helper window has been closed. If not set, uses the size of the whole screen. single_main_window_move ivec[2] Location to snap the main window to when the helper window has been closed. If not set, uses (0, 0). fit_page_to_width_ratio float Ratio of page width to use for fit_to_page_width_ratio command. A value of 1 would use the whole window width for the page. collapsed_toc boolean If set, we initially collapse table of content entries. ruler_mode boolean If set, we highlight the current line in visual_scroll_mode by mask- ing above and below the current line. If not set, we only mask below the line. ruler_padding float Ruler padding between the edges of the top and bottom of the text and the ruler. ruler_x_padding float Ruler padding between the edges of the left and right of the text and the ruler. text_summary_url string Text summary url for fastread. Fastread mode (turned on with the command toggle_fastread) by default queries a url for information about which characters of each word on the page to highlight. An im- plementation of such a server based on a language model is available here: https://github.com/ahrm/sioyek/blob/main/scripts/summary_high- light_server.py. By default, both this script and sioyek will bind to localhost:5000. text_summary_should_refine boolean Language model option for the fastread server program. If 1, then prevent highlights in the middle of words by always highlighting starting from the beginning of the word until the first mispredicted character. text_summary_should_fill boolean Language model option for the fastread server program. If 1, then highlight the entire word when over 50% of it is highlighted. text_summary_context_size integer Context size to use on the fastread server. Number of characters in context for next character prediction. use_heuristic_if_text_summary_not_available boolean Use heuristic if text summary url does not return highlights. The heuristic involves choosing ceiling(length*0.3) characters of every word to emphasize. papers_folder_path string A directory which sioyek watches for new papers. If a new paper added to this directory while we are creating a portal from another document, this new document will automatically be used as the desti- nation of the portal. enable_experimental_features boolean Enable possibly unstable experimental features create_table_of_contents_if_not_exists boolean Automatically create a table of contents for the document if it doesn't already have one. max_created_toc_size integer Limits the maximum size of created table of contents. force_custom_line_algorithm boolean Use custom algorithm based on pixmaps to compute rectangles around the lines of the document. overview_size fvec[2] Size, width and height, of the overview window. The overview window is triggered by right clicking on an internal link, or hovering if hover_overview is set to 1. overview_offset fvec[2] Offset of the overview window as floats from the center of the page. ignore_whitespace_in_presentation_mode boolean Always use fit_to_page_smart (ignoring whitespace) in presentation view. exact_highlight_select boolean If set to 0, then in word select mode, select the whole word even if the cursor is only partially on the word. If set to 1, then select the word only if the range of the cursor's selection fully includes the word. show_doc_path boolean If set to 0, then only show the filename in the dialog to choose to open a previous doc (open_prev_doc). If 1, then show the entire file path. fastread_opacity float Opacity of the dimmed portion of words in fastread mode. highlight_color_* color_3 Color of the highlight color bound to symbol * (should be one char- acter). should_warn_about_user_key_override boolean If set to 0, then don't warn the user about key definition overrides when the two definitions are in different files. If set to 1, then always warn the user when keys are overridden. single_click_selects_words boolean If set to 0, then single clicks select words and double clicks allow selection of arbitrary ranges of characters. If set to 1, then dou- ble clicks select words and single clicks allow selection of arbi- trary ranges of characters. highlight_middle_click boolean If set to 1, then middle clicks add a highlight with select_high- light_type when a selection is active and no preview is open. If set to 0, a smart jump is always attempted. super_fast_search boolean If set to 0, search is performed by the mupdf backend. If set to 1, a super fast search index is used instead. This leads to a slight increase in memory. case_sensitive_search boolean If set to 1, search and regex_search are case-sensitive. If set to 0, search and regex search are case-insensitive. incremental_search boolean If set to 1, jump to the first result as soon as you start typing. If set to 0, wait until enter is pressed.
